Former Sonics star Shawn Kemp is hosting a pre-vote arena rally on Sunday

Former Sonics star Shawn Kemp is planning a public rally in support of the proposed basketball arena on Sunday, one day before the Seattle City Council is slated to vote on legislation to help finance the venue.

The “Rally with the Reign Man” is scheduled for 3 p.m. Sunday at Oskar’s Kitchen, the Lower Queen Anne restaurant that Kemp and his wife, Marvena, opened in December. It’s at 621 1/2 Queen Anne Ave. N. across from the MarQueen Hotel.

Admission is free. But, this time, it doesn’t look like investor Chris Hansen will be buying everyone a beer. The 21-plus rally will, however, feature cocktails inspired by the Seattle Sonics, according to the event announcement.

Kemp will be joined by Sonics legend Slick Watts and his son Donald Watts, a former basketball star at the University of Washington, in giving away memorabilia and posing with fans for photos. Also on the guest list are local filmmakers Jason Reid and Adam Brown, whose “Sonicsgate” documentary tells the controversial story of the Sonics’ departure from Seattle.

Hansen, who held his own rally at F.X. McRory’s last week when his arena proposal was in front of a City Council committee, is not slated to be at the “Rally with the Reign Man.” But the organizers do expect hundreds of fans to show up wearing green and gold.
